In an exemplary embodiment, second unit 20 may be about 2-3 inches in length by approximately 1 inch in width.
Now referring to FIGS. 8-10, First unit 10 and second unit 20 may be simple, effective, and user friendly devices with a variety of operational components. In an exemplary embodiment, first unit 10 and second unit 20 may each include one or more of: an alert button 40, a time delay module 42, a transmitter 44, an antenna 46, a receiver 48, an audio generator 50, a speaker 52, a light emitting diode (LED) 54, an electromechanical transducer 56, an identification module 58, a microcontroller or microprocessor 60, a power source 62, an on/off switch 64, a voltage regulator 66, a proximity device 68, a distance gauge 70, a distance indicator display 72, an anti-tampering device 74, or a combinations thereof. Notably, first unit 10 and second unit 20 may be designed so as to only consist of a limited selection of these operational components in order to produce a simple device that may be easily and intuitively operated in emergency situations. Additionally, first unit 10 and second unit 20 may have different operational components. FIGS. 8-10 show exemplary embodiments of the first unit 10 and second unit 20 including different combinations of the aforementioned operational components, the functions for which are described below.
A remote locator unit 10, 20 of the present invention may include an alert button or switch 40 electrically connected to a transmitter 44. When alert button 40 is depressed, the transmitter sends a signal to a receiver 48 in a corresponding remote locator unit 10, 20 to activate an alarm. The alert button 40 may be designed to prevent accidental activation. In one embodiment, alert button 40 may have a time delay activation feature. For example, a time delay module 42, which may be any conventional time delay circuit, accepts an input signal from alert button 40 and after a predetermined delay period passes the input signal to transmitter 44. Time delay module 42 may be set to any time delay interval; in an exemplary embodiment, the time delay interval may be about five seconds or less. Accidental activation may also be avoided by countersinking alert button 40 relative to the remote locator unit 10, 20.
Upon activating alert button 40, transmitter 44 emits a radio frequency signal to be received by corresponding receiver 48. Transmitter 44 may generate a signal at any suitable frequency on any designated bandwidth, preferably a high frequency on an approved FCC bandwidth. In an exemplary embodiment, the frequency may be within the range of about 1-1,500 MHz, preferably about 315-1,500 MHz, and the transmission bandwidth may be about 433 MHz. Transmitter 44 may be able to communicate with receiver 48 at these frequencies over long distances. In an exemplary embodiment, transmitter 44 may communicate with receiver 48 over a distance of about 0-200 ft, preferably, about 0-150 ft.
Radio frequency signals from transmitter 44 to receiver 48 may be transmitted and received using antenna 46. As shown in FIGS. 1-4, antenna 46 may be a loop type antenna embedded along the perimeter of the first unit 10 and/or an extension antenna located in the housing of second unit 20. Other antennas, such as microwave, dipole and multiple arrays, may also be used.
Upon depressing alert button 40, a signal is sent from transmitter 44 to receiver 48 to activate an alarm to produce an emergency alert. The emergency alert may be any indicator that would draw attention to and facilitate the location of a remote locator unit 10, 20. Preferably, the emergency alert may also draw the attention of individuals located proximate to the remote locator to signal an emergency situation. In an exemplary embodiment, the emergency alert may be an audible sound, a visual display or other indicator. Specifically, the emergency alert may be a loud, repeated and/or high pitched noise, such as a beep or horn, generated by audio generator 50 and speaker 52 and/or a light generated by LED 54 that illuminates, flashes and/or changes color. The signal may also induce a remote locator unit 10, 20 to vibrate by activating an electromechanical transducer 56 in order to notify the individual carrying the vibrating unit that he is being sought. In an exemplary embodiment, upon depressing alert button 40, the emergency alert may become louder, brighter, change colors or emit more frequent sounds, flashes or vibrations as first unit 10 and second unit 20 draw closer to one another. Additionally, an audio generator 50 and speaker 52, LED 54, or electromechanical transducer 56 of the corresponding remote locator unit may also emit sounds, lights and/or vibrations as first unit 10 and second unit 20 draw closer together.
The various components and the overall operation of the remote locator units 10, 20 may be controlled by a microcontroller or microprocessor 60. As shown in the exemplary circuit diagram of FIG. 10, microcontroller 60 may control the activation of transmitter 44, encrypt transmission signals between digital and analog, identify signals received from transmitter 44 and control alarm activation.
In one embodiment, microprocessor 60 may incorporate or may be operatively connected to an identification module 58, which functions to prevent errant signals from interfering with the operation of the remote locator system and to ensure secure transmissions. Identification module 58 may be a functionally integral feature of microprocessor 60 and/or the circuitry of remote locator units' 10, 20. Alternatively, microprocessor 60 may be a functionally integral feature of identification module 58. According to one embodiment, identification module 58 may generate and/or recognize a unique digital binary electronic signature that is unique to each remote locator system. This enables corresponding remote locator units 10, 20 of the same system to send and receive information with one another without signal interference.
Additionally or alternatively, identification module 58 may prevent signal interference by selecting a unique frequency on which the remote locator units 10, 20 communicate. In an exemplary embodiment, each time the remote locator units 10, 20 are turned on, identification module 58 may randomly select a unique frequency out of at least 1,500 possible communication channels after an initial activation of alert button 40. In one embodiment, the communication frequency may be within the range of about 1-1,500 MHz, preferably about 315-1,500 MHz. This step of selecting a communication frequency, i.e. arming the remote locator system, involves the process of pressing alert button 40 after the remote locator units 10, 20 are first turned on. The initial activation of alert button 40 induces identification module 58 and/or microprocessor 60 of second unit 20 to randomly select a communication channel and send a signal to first unit 10 to set the communication frequency. The selected communication frequency may be impressed on identification module 58 and/or microprocessor 60 of first unit 10. Second unit 20 and impressionable first unit 10 should be positioned within a few feet, preferably, less than about 10 feet, more preferably, less than about 5 feet, of one another in order to arm the remote locator unit. Alternatively, first unit 10 may select, establish and transmit a chosen communication frequency to an impressionable second unit 20. Upon arming the remote locator system, first unit 10 and/or second unit 20 may produce an audio, visual or other arming confirmation indicator to notify a user that a communication frequency has been established. For example, an audio generator 50 and speaker 52 may emit one or more sounds, such as a beep, an LED 54 may illuminate, flash and/or change color, and/or an electromechanical transducer 56 may vibrate.
In an exemplary embodiment, identification module 58 is an inherent feature of microprocessor 60 and microprocessor 60 controls the selection, impression and establishment of a unique transmission frequency to enable communication between receiver 48 and transmitter 44 without interference from other remote locator systems or other radio frequency signal sources and/or generate and/or recognizing a unique digital binary electronic signature that is unique to each remote locator system. Microprocessor 60 may also control other operational features of the remote locator units 10, 20.
The remote locator units 10, 20 of the present invention each contain their own power source 62. Power source 62 may include a battery, a photovoltaic device, or any portable power supply means. In an exemplary embodiment, the power source 62 may be a 12 volt micro battery or a 2030 wafer battery. Preferably, the power source 62 may be a rechargeable power source that may be coupled to or cradled in a charging device in order to reenergize power source 62.
The power source 62 may be connected to an on/off switch or button 64. In an exemplary embodiment, the on/off switch 64 of first unit 10 may be inconspicuous, obscured and/or difficult to locate in order to avoid detection. The on/off switch 64 of first unit 10 may also be operatively associated with an anti-tampering device 74 which prevents first unit 10 from being turned off without first providing a designated signal, code or key. In one embodiment, the signal may be transmitted by second unit 20. In another embodiment first unit 10 may include a key pad for entering a code or key hole for receiving a key. The key may be attached to and/or removably housed in a compartment of second unit 20.
Power source 62 may be connected to a voltage regulator 66 that monitors the available amount of energy to operate the remote locator unit 10, 20 stored in power source 62. When the measured voltage drops below a predetermined level, such as about 2.6 V, voltage regulator 66 sends an electrical signal to microcontroller 60 to activate an alarm to produce a low power warning. For example, the low power warning may be manifested by the illumination, flashing and/or color change of LED 54; a sound, such as a beep or chirp, generated by audio generator 50 and speaker 52; and/or the vibration of electromechanical transducer 56. In an exemplary embodiment, voltage regulator module 66 will provide a low power warning at least 24 hours in advance of complete power depletion.
In an exemplary embodiment shown in FIG. 9, the remote locator unit 10, 20 may include a proximity device 68 that is capable of monitoring and/or measuring the distance between the first unit 10 and second unit 20. In one embodiment, a microcontroller 60 and transmitter 44 of one remote locator unit may be programmed to send a continuous and periodic stream of homing signals. The homing signals may be received by a receiver 48 of a corresponding remote locator which is electrically connected to proximity device 68 and microcontroller 60. By analyzing the signal strength and/or time intervals between the received homing signals, proximity device 68 and/or microcontroller 60 may monitor and/or measure the distance between the first unit 10 and second unit 20. In an exemplary embodiment, the first unit 10 and second unit 20 are both sending as well as receiving the homing signals. For example, proximity device 68 may be electrically connected to receiver 48 to detect a constant stream of periodic electronic homing signals from a remote locator unit 10, 20 and may also be electrically connected to a transmitter 44 to send periodic homing signals.
When the remote locator units 10, 20 are separated by such a large distance that they can no longer communicate with one another, proximity device 68 may direct microcontroller 60 to activate an alarm to produce a proximity breach warning and/or emergency alert. Alternatively, a proximity breach warning and/or emergency alert may be produced when proximity device 68 determines that the distance between two remote locator units 10, 20 have exceeded a preset distance. In an exemplary embodiment, the preset distance may be about 25 feet, 30 feet, 50 feet or 100 feet. Optionally, proximity device 68 may include a distance gauge 70 or other means for adjusting and setting the preset distance. In an exemplary embodiment, the proximity breach warning may be manifested by the illumination, flashing and/or color change of LED 54; a sound, such as a beep or chirp, generated by audio generator 50 and speaker 52; and/or the vibration of electromechanical transducer 56. The warning may prompt a user to press alert button 40, activating the alarm to produce an emergency alert. Alternatively, proximity device 68 may automatically activate an emergency alert.
Proximity device 68 may also enable second unit 20 to periodically monitor and track the location of first unit 10. In one embodiment, a distance indicator display 72 may be operatively connected to proximity device 68 to show the distance separating the first unit 10 and second unit 20. The proximity device 68 may determine the position of as well as relative direction and distance between of the first unit 10 and second unit 20. In an exemplary embodiment, the proximity device 68 may activate the alarm to produce a tracking indicator. For example, proximity device 68 may instruct microprocessor 60 to activate: audio generator 50 and speaker 52 to produces different, louder, softer, longer, shorter and/or more frequent sounds; LED 54 to change color, change visual displays, and/or increase flash frequently; and/or electromechanical transducer 56 to increase the frequency of vibration, as first unit 10 and second unit 20 draw closer together.
The remote locator system of the present invention may be programmed such that the tracking indicator, arming confirmation indicator, low power warning, proximity breach warning, emergency alert, and other alerts and indicators of the present system may be distinct from one another to avoid confusion. Each alert or indicator may have a unique sound, sound volume, sound duration, sound frequency, visual display, visual display frequency, vibration or combination thereof.
The present invention has been described with reference to the enclosed preferred embodiment. It is to be appreciated that the other embodiments may fulfill the spirit and scope of the present invention and that the true nature and scope of the invention must be determined with respect to the claims appended hereto.
